Clinical validation during anesthesia of the Dräger PulmoVista 500 monitor.

The study is designed to investigate the efficacy of the Drager PulmoVista 500 monitor in different conditions of ventilation, during anesthesia.

The bedside efficacy of the Dräger PulmoVista 500 monitor in intensive care settings during mechanical ventilation is known. The present study will demonstrate its utility (if any) during anesthesia.

Before and after induction of anesthesia, during two and one-lung ventilation, during high frequency jet ventilation for bilateral thoracoscopy versus one-lung ventilation, in all cases before the start of the surgery.

Monitoring of lungs using the PulmoVista 500 lung monitor during anesthesia in different conditions:

1. Comparison of airway devices: Spontaneously breathing patients, ETT and general anesthesia, LM and general anesthesia, mask ventilation and general anesthesia, during epidural/spinal anesthesia;

2. During laparoscopic surgery in three classical positions – supine, Trendelenburg and reverse Trendelenburg;

3. During two and one-lung ventilation in the supine position with closed chest;

4. During High frequency jet ventilation versus one-lung ventilation.
